I'm not worried yet. Hillary can lose all the light blue states (FL, NV and NC). Her "firewall" (who named it that?) is still holding. It'd be better for the country if it'd gone more solidly blue but Trump needs to punch through one of her deeply blue states. That isn't happening at this point.

All Hillary needs to do is take one light bue state to ruin it for Trump.
